Tiivistelmä
This thesis project explored the possibility of a comprehensive sound level monitoring device on recently developed components, in collaboration with TJK Tietolaite Oy to ensure the real-life practicality of the end product. The device’s goal was to monitor sound level continuously and communicate wirelessly over long distances.
The project examined the requirement of the IEC 61672-1:2013 and based on these requirements, build a proof-of-concept of the device, using MEMS microphone. STM32 Nucleo-H742ZI development board and the CMSIS DSP library.
The project was able to build a functional prototype that could give sound level measurment. However, its performance was not adequtely asserted and finely calibrated due to a lack of equipment as a result of the current Covid-19 pandemic.
